comprisedof 5modules
A singleSampleProcessingUnitwitha standard split/splitless injectionport (1:1up to1:200) suitablegasand liquid
samples viaeither syringe through the septum injections, optional gas, liquidor headspaceauto-sampler, or
automated samplingvalves. The inlet includes septumpurge toprevent bleed components fromentering the system.
The sample is thendelivered toa column switchingvalve for analysison two independent columnmodules.

columnmaterial selected. Each columnmodule is independently controlledby themethodand canbeanyof the
available column types.
Two independentDetectorModules incorporatingeither amicro Flame IonizationDetector (FID) ormicroThermal
ConductivityDetector (TCD)with thenecessaryhardware, softwareandelectronic control toprovidedetector
temperature control, digital output signal andadditionally for proper FID fuel supplypressureandauto-ignition.
ThemicroFID is a fullydigital carbon/hydrogenbonddetectorusing thehydrogen flame toburn the sample
components. It uses anelectrometer to sense the current changes in the flame cell due to chromatographic
component elution. Thedata rate is100Hz.
ThemicroTCD is a fullydigital, universal detector. TheTCD consistsof a constant temperature filament that
senses change inpower required tohold the filament temperature constantwhen chromatographic
components elute. Thepowermeasurement isused todetermine theamount of the component eluting from
the column. Thedata rate is 50Hz.
CALIDUS is controlledwithChromPerfect chromatographydata system fully integratedwith LineUp runningona

SIGNIFICANCEANDUSE
TheModel CSprovides a simpleultra-fast analysis (10 to50 times faster than conventional labor process
GC’s) of fixedgases andhydrocarbons toC
12
. Useof twodifferent PTCMswith their owndetectors
separatedby the column switchingvalvewith theappropriate columnmaterial enables leveraging the
sensitivityand selectivitydifferences for enhanced separations (for exampleheartcuts andbackflushing).
Proper choiceof columnsenableswideboiling rangeand concentration rangeswitha singleGC. Model CS
is ideal for individual component speciation fromother samplematrix components.
Theanalyses areused for product specifications testing, product safety, environmentalmeasurements,
process control, catalyst protection, educational tools, spot checksof fuels andmanymore.
